The value of x is 7
Solution:
Given that we have to solve the proportion
[tex]\frac{9}{10} = \frac{9x}{70}[/tex]
We can solve the proportion by cross multiplying
Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction
Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction
Set the two products equal to each other
Solve for the variable
Therefore,
[tex]\frac{9}{10} = \frac{9x}{70}\\\\9 \times 70 = 9x \times 10\\\\x \times 10 = 70\\\\x = 7[/tex]
Thus value of "x" is 7
